GOTTFRIED FERDINAND KRIEGER, OF KIEL, GERMANY.

ELECTRIC lGNlTlNG DEVICE FOR GAS BURNERS.

SPECIFICATION forming part of Letters Patent No. 571,769, dated November 24, 1896.

Application filed May 4, 1896. $erial No. 590,188. (No model.)

To 031% whom it may concern:

Be it known that I, Go'rrnnrnn FERDINAND KRIEGER, a subject of the German Emperor, and a resident of Kiel, in the German Empire,

have invented certain new and useful Imauxiliary iguiting-tube already existing in.

many burners. Moreover, all of the more delicate parts of the device are remote from the igniting-flame.

The object of my invention is to procure a simple, cheap, and. reliable igniting device.

In the accompanying drawings I have shown how my invention may be conveniently and advantageously carried into practice.

Figures 1 and 2 represent side elevations of the igniting device, taken at right angles to each other. Figs. 3 and i are similar views showing the different parts of the igniting device in their operative position.

Similar letters refer to similar parts throughout the similar views.

To a bracket or clip I carried by the b urnertube 6, a two-armed lever c is pivoted at 1). Into the top extremity of this lever a small steel pin 0 is screwed, and into the tubular lower extremity a sliding pin or plunger 0 is inserted, the outer extremity of which pin or plunger engages with an arm CZ, arranged on the plug cl of the gas-cock. Further, a spring f, insulated from the bnrner-tube e and extending in the direction of the aforesaid lever c, is fixed to a plate 7" on the bracket 1) aforesaid. This plate f is by means of screws f connected to one pole of a source of electricity, whose other pole is connected to the me tallic gas-burner tube 6, which is placed into the circuit.

The before-described parts can, as above mentioned, be made separately. The bracket 1) is placed around the burner-tube e, the arm (1 is fixed on the plug d of the cock, and the sliding pin or plunger 0 is connected to the said arm (1 on the one hand and is inserted in the tubular extremity of the lever c on the other hand. The constituent parts are so mounted together relatively to one another, to the plug of the cock, and to the ignitingtube a, which latter is located in an opening or suitable slot of the bracket 1), that the pin a at the upper end of the lever a, while the cock is being opened and the lever thus turned around its axis 1), engages or comes in contact with the upper extremity of the spring j and carries it over the orifice of the ignitingtube a by bending the spring f. (See Figs. 3 and Gas then lows into the ignitingtube (.1, and to the burner, and the pin 0 of the lever c then releases the spring f by sliding over the extremity of the spring, which then moves back rapidly and breaks the circuit which was closed. by the contact of the lever-pin c with the springf. This circuit in eludes an clectromagnct. The electric spark produced above the igniting-tube CL ignites the gas leaving the said tube, and the small flame thus produced then instantly ignites the gas discharged from the burner-tube e and is subsequently extinguished, since by the further opening movementof the cock the further supply of gas to the igniting-tube a is out off. The spring f never comes in contact with the igniting-flame, and consequently wears but very little.

lVhen the cock is turned back to its closing position, the pin 0 of the lever 0 comes in contact with the extremity of the spring f on the other side and bends the spring in the opposite direction. The said pin c during this operation slides upon the spring in a downward direction until it comes opposite a notch f in the spring f, whereupon the latter, being thus liberated, returns to its normal position, and the contact-m aking pin 0 is thus brought back to the other side of the spring f.

The oscillating movement of the lever c is produced by the small sliding pin or plunger 0 the lower extremity of which is moved by the arm d of the rotating plug cl of the cock, while the said sliding pin or piston c is caused to slide to and fro in the tubular extremity of the lever c. The employment of this link between the plug 66 of the gas-cock and the lever c and the use of the bracket 1) allow of an easy adaptation of the device to burners with various lengths of cock, since the bracket Z) can be fastened at a variable height on the burner.

The abovedescribed igniting device is applicable to gas-burners in which the longitudinal axis of the casing of the cock lies in a straight line with the axis of the burner as well as to such burners in which these axes are inclined to one another.

Having fully described my invention, what I desire to claim and secure by Letters Patent is 1. An electric igniting attachment for gasburners consisting essentially of a clip or strap adapted to be secured to the burner, a spring and a two-armed rook-lever, respectively secured to and pivoted on said strap, one of the arms of said lever provided with a suitable contact adapted to impinge upon the spring and flex the same'and having its other arm constructed telescopically and adapted for connection with the plug of a gas-cock substantially as and for the purpose set forth.

2. An electric igniting attachment for gasburners consisting essentially of a clip or strap adapted to be secured to the burner, a spring provided at its free end with a recess or cutaway portion f and a two-armed rock-lever respectively secured to and pivoted on said strap one of the arms of said lever provided with a suitable contact adapted to impinge upon the spring and flex the same and having its other arm constructed telescopically and adapted for connection with the plug of a gascock substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in pres ence of two witnesses this 20th day of April. 1896.
